The term used to describe a way of positioning your vehicle's windows so that they are 3/4 of the way rolled up. If the vehicle has rear windows, those windows should line up exactly with the front. This also accentuates the lines of the car and creates a smooth look while rollin through the hood. It is not uncommon to see this on a beater that has a purple flake paint job and twinkies but hasn't bothered to fix his A/C.
